Opfindelsen angår en fremgangsmåde til isolering af tage på oliebeholdere o. lign. bygningsværker, hvor isoleringen består af en folie, som dækker et varmeisolerende materiale og holder dette på plads, samt af organer til fastgørelse af 5 folien, hvilke' fastgørelsesorganer hver omfatter mindst en skive og en skruetap, hvis ene ende er forsynet med gevind, hvorhos skiven er indrettet til fastgørelse på skruetappens øverste ende med den side af skiven, som ligger an mod folien, hvilket fastgørelsesorgan er fastsvejset på oliebeholde-10 rens tag, hvorhos skruetappens længde er afpasset således, at skiven ved tilspænding kommer til at ligge an mod folien med tryk.The invention relates to a method for insulating roofs of oil containers and the like. buildings in which the insulation consists of a foil covering a heat-insulating material and holding it in place, as well as means for securing the foil, each of which having at least one washer and a screw pin, one end of which is provided with threads, the disc is arranged for attachment to the top end of the screw pin with the side of the disc abutting the foil, which securing means is welded to the roof of the oil container 10, the length of the screw pin being adjusted so that the disc will abut against the foil by tightening with pressure.

Til isolering af tage på oliebeholdere har man hidtil først lagt et isoleringsmateriale på og derefter oven på det-15 te en aluminiumplade som beskyttelse. Aluminiumspladerne sammenføjes ved falsning, normalt dobbeltfalsning. Man får derved en fast forbindelse uden mulighed for, at pladerne bevæger sig indbyrdes. Det har vist sig, at der opstår revnedannelse i pladerne på grund af varmespændinger. Ved utætte be-20 skyttelsesplader udsættes isoleringsmaterialet for fugt, snavs o.lign. Fugten trænger ind i isoleringsmaterialet og når selve taget. Dette kan medføre korrosion af taget, som dermed kan ruste væk. Aluminiumplade er desuden meget dyr, hvilket sammen med den relativt dyre og tidsforbrugende frem-25 gangsmåde til falsning gør hele isolationen dyr.To insulate roofs on oil containers, an insulating material has so far been applied first and then on top of that an aluminum plate for protection. The aluminum sheets are joined together by folding, usually double folding. This gives a fixed connection without the possibility of the plates moving between them. It has been found that cracking occurs in the plates due to heat stresses. In leaking protective plates, the insulation material is exposed to moisture, dirt and the like. The moisture penetrates the insulation material and reaches the roof itself. This can cause corrosion of the roof, which can thus rust away. Furthermore, aluminum sheet is very expensive, which together with the relatively expensive and time-consuming method of folding makes the whole insulation expensive.

Til grund for den foreliggende opfindelse liger den opgave at tilvejebringe en fremgangsmåde til isolering af tage, der er let at anbringe, er billig og ikke har tendens til revnedannelse. Denne opgave løses ifølge opfindelsen ved, at 30 der først fastgøres et antal skruetappe på taget ved svejsning ved hjælp af en svejsepistol på en sådan måde, at skruetappene bliver opretstående, at isoleringsmaterialet derpå stikkes på skruetappene og lægges på taget, at isoleringsmaterialet derpå dækkes med en af lange, indbyrdes overlappende 35 banelængder bestående, vandugennemtrængelig folie, som pres- - 2 -The object of the present invention is to provide a method of insulating roofs which is easy to apply, is inexpensive and does not tend to crack. This task is solved according to the invention by first attaching a plurality of screw pins to the roof by welding by means of a welding gun in such a way that the screw pins are upright, that the insulating material is then inserted on the screw pins and laid on the roof, that the insulating material is then covered with one of long, overlapping 35 web lengths consisting of water impervious film which presses - 2 -

ses ned over skruetappene, som således kommer til at stikke op gennem folien, og at skiverne derpå skrues på skruetappene. Med en fremgangsmåde til isolering ifølge opfindelsen slipper man for ulemperne ved varmespændinger, og man får en 5 god og billig isolering, som er let at anbringe og holder helt tæt.can be seen down over the screw pins, which will thus protrude through the foil and that the washers are then screwed onto the screw pins. With a method of insulation according to the invention, the disadvantages of heat stress are avoided and a good and inexpensive insulation is obtained which is easy to apply and holds very tight.

Opfindelsen forklares i det følgende nærmere under henvisning til tegningen, hvor 10 fig. 1 viser en udførelsesform for et fastgørelsesor gan til anvendelse ved fremgangsmåden ifølge opfindelsen, set fra siden, fig. 2 viser en anden udformning af et sådant fastgørelsesorgan, set fra siden, 15 fig· 3 viser en del af en oliebeholder, set fra si den, fig. 4- viser samme parti set ovenfra, fig. 5 viser et tværsnit gennem isoleringen ved over gangen mellem beholderens tag og væg, 20 fig· 6 er en principskitse for en svejsepistol til fastgørelse af skruetappe, og fig. 7 viser en fastsvejset skruetap, set fra siden.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail with reference to the accompanying drawings, in which 1 is a side view of an embodiment of a fastener for use in the method of the invention; FIG. 2 is a side view of another embodiment of such a fastener; FIG. 3 is a partial view of an oil container; FIG. 4 is a plan view of the same portion; FIG. 5 shows a cross-section through the insulation at the passage between the roof and the wall of the container; FIG. 6 is a schematic sketch of a welding gun for fixing screw pins; and FIG. 7 is a side view of a welded screw pin.

På taget 1 af en beholder fastgøres ved hjælp af en 25 svejsepistol 2 (fig. 6) en skruetap 3, som i sin ene ende 4 er forsynet med gevind og ved sin anden ende 5 er forberedt til svejsning ved hjælp af en svejsepistol. Enden 5 har en lille centertap 6 (jvf. fig 6), som placerer svejsningen i tappen 3’s akse. Tappene 3 fordeles med ensartet afstand ved 30 hjælp af en skabelon. Derefter anbringes isolationsmaterialet 7 (fx. stenuldsplader) således, at tappene 3 trænger op gennem isolationsmaterialet. Dette dækkes med en foliebeklædning 8. Foliebeklædningen kan hensigtsmæssigt bestå af en blød PVC-vævsplast, idet en sådan har en god slidstyrke og en god 35 modstandsevne mod kemikalier. Foliebeklædningen 8 fås i rul- - 3 -On the roof 1 of a container is secured by means of a welding gun 2 (Fig. 6) a screw pin 3, which at one end 4 is threaded and at its other end 5 is prepared for welding by means of a welding gun. The end 5 has a small center pin 6 (cf. Fig. 6) which places the weld in the axis 3 of the pin 3. The pins 3 are distributed at a uniform distance by means of a template. Then, the insulation material 7 (e.g., rock wool boards) is placed so that the pins 3 penetrate through the insulation material. This is covered with a foil liner 8. The foil liner may conveniently consist of a soft PVC tissue plastic, having a good abrasion resistance and a good resistance to chemicals. The film cover 8 is available in roll - 3 -

ler, som rulles ud i lange baner på taget 1. Man skal sikre sig, at banerne overlapper hinanden. Ved hjælp af skabelonen har man anbragt en del af tappene i de områder, hvor overlapningerne skønnes at blive lagt. Tappene 3’s længde er afpas-5 set således, at de bliver noget længere end den samlede tykkelse af isoleringsmaterialet 7 og foliebeklædningen 8. Foliebeklædningen presses ned over tappene, således at disse kommer til at stikke op over folien. Derefter påskrues skiver 9, som er forsynet med indvendigt gevind på den side 10, som 10 er beregnet til at ligge an mod folien, på den øvre ende 4 af tappene 3· Et bindemiddel 11 lægges på folien 8 under skiverne 9· Skiverne er forsynet med forsænkninger 12, som gør det muligt at tilspænde skiverne ved hjælp af et passende værktøj (ikke vist). Skiverne 9 tilspændes således, at de kommer til 15 at ligge an mod foliebeklædningen 8 med tryk.clay that is rolled out in long lanes on the roof 1. Make sure the lanes overlap. Using the template, some of the tabs have been placed in the areas where the overlaps are estimated to be placed. The length of the pins 3 is adjusted so that they become somewhat longer than the total thickness of the insulating material 7 and the foil coating 8. The foil coating is pressed down over the pins so that they protrude over the foil. Then screws 9, which are provided with an internal thread, on the side 10 which 10 is intended to abut against the foil, on the upper end 4 of the pins 3 · A binder 11 is applied to the foil 8 under the discs 9 · The discs are provided with countersinks 12, which enable the slices to be clamped by a suitable tool (not shown). The discs 9 are tightened so that they come into contact with the foil covering 8 with pressure.

Fig. 2 viser en anden udformning af fastgørelsesorganet til anvendelse ved fremgangsmåden ifølge opfindelsen. Ifølge dette eksempel anvendes der en skruetap 13 af standardtype til fastsvejsning med svejsepistol. Skruetappene 13 er for-20 synet med gevind over hele længden og har også en centertap 6, se fig. 6. Med gevind i begge ender 23, 24 forsynede bøsninger 14 skrues med deres ene ende på tappene 13· I den anden ende 24 af en bøsning indskrues en stang 15» som har udvendigt gevind i begge ender 25, 26. På samme måde som ved 25 den første udformning anbringes derefter isoleringsmateriale og foliebeklædning. Den samlede længde af stangen 15, bøsning 14 og tappen 13, når disse er indbyrdes fastgjort ved hinanden, er noget større end den samlede tykkelse af isoleringsmaterialet og foliebeklædningen. Efter at foliebeklædningen 30 er trykket ned over stængerne 15, skruer man ved hjælp af et værktøj (ikke vist) stangen et lille stykke op, dog ikke så langt, at den skrues op af bøsningen (eller at bøsningen løsnes fra tappen). Stangen holdes fast, medens en skive 9, som er lige som den i den første udformning, skrues på samme.FIG. 2 shows another embodiment of the fastener for use in the method according to the invention. According to this example, a standard type 13 screw pin is used for welding gun welding. The screw pins 13 are provided with threads over the entire length and also have a center pin 6, see fig. 6. Threaded bushes 14 at both ends 23, 24 are screwed with one end to the pins 13 · At the other end 24 of a bushing screw a rod 15 »having external threads at both ends 25, 26. In the same way as In the first embodiment, insulating material and foil coating are then placed. The total length of the rod 15, bushing 14 and the pin 13, when attached to each other, is somewhat greater than the total thickness of the insulating material and the foil coating. After the foil lining 30 is pressed down over the rods 15, the tool is screwed up (not shown) a short distance, but not so far that it is unscrewed from the bushing (or the bushing is detached from the pin). The rod is held in place while a washer 9, similar to the one in the first embodiment, is screwed onto the same.

Fig. 5 er et tværsnit gennem isoleringen, af hvilket det 15 fremgår, hvorledes denne udføres ved overgangen fra væg til tag. Dette foregår således, at en vægisolering 16 på væggen er anbragt på plads og derefter beklædt med plader 17· På taget fastgør man først skruetappene 13, hylstre 14 og stænger 15 på den overfor beskrevne måde. Rundt om hele 20 beholderen anbringes et kantbeslag 18, som fastgøres med nitter 19 på pladerne 17· Kantbeslaget 18 kan bestå af stålplade, på hvilken der påføres en PVC-lak^ Isoleringsmaterialet 7 lægges på taget, og man sørger for, at det ligger helt ud kantbeslaget 18. Foliebeklædningen 8 25 rulles derefter på og lægges oven på kantbeslaget, hvor den fastsvejses til PVC-lakken.FIG. 5 is a cross-section through the insulation, which shows how it is carried out at the transition from wall to roof. This is done so that a wall insulation 16 on the wall is placed in place and then covered with plates 17 · On the roof, first fasten the screws 13, sleeves 14 and rods 15 in the manner described above. Around the entire 20 container is placed an edge bracket 18, which is fastened with rivets 19 to the plates 17 · The edge bracket 18 may consist of steel plate, to which a PVC lacquer is applied ^ The insulation material 7 is laid on the roof and made sure it is completely out the edge bracket 18. The foil liner 8 25 is then rolled on and placed on top of the bracket where it is welded to the PVC lacquer.
